Chen Mochen, a data entry clerk, has a monthly salary that is just enough to pay the rent. In 2057, the sky was filled with skateboards and taxis, and because he couldn't afford the annual aircraft inspection fee, he had to take the subway and go to Qingshiban Alley to set up a stall. Selling camping stoves, self-heating pots, and folding chairs - specifically for low-level hikers who can't afford to fly aircraft. Until late at night, a system claiming to be "Mozart" popped up: "The stall is out of bounds? Domain conflicts will summon undercurrents." Chen Mozhen didn't take it seriously. The next day, a rich second-generation man in a flight jacket deliberately flew by at a low altitude, and the airflow overturned his box of prepared vegetables. System Flash: Consume fireworks gas to counterattack. He silently lit the charcoal fire, and the aroma of the barbecue turned into reality. He dragged the rich second generation down with his skateboard and threw him until he was chewed in the mud. Onlookers were dumbfounded: "Can you cultivate immortality by setting up a stall?" What's even weirder is that the five-year-old daughter Xiaohe always points to the open space at two o'clock in the morning: "Dad, the shadow is crying." The undercurrent - the supernatural energy condensed by human negative emotions, is corroding the entire city. Only the pyrotechnics of the camping campfire and the lively operation can open the door to the Shadow Market. When the flying noble laughed at him as an ant on the ground, his sales surged overnight and slapped him in the face; when the bluestone alley was swallowed up by the undercurrent, Xiaohe's words "Uncle, you have a dirty heart" made the evil spirit freeze. The last rule of the system: If you go to Shadow Market at three o'clock in the morning, you must return before dawn, otherwise... Chen Mowen discovered that what he was guarding was not just the stall, but the last human touch of the entire community.
